Whats Sklauncher [OFFICIAL]

What is SKLauncher SKLauncher is a third-party Minecraft launcher that provides an alternative way to launch and manage Minecraft instances, mods, resource packs, and profiles. It typically offers features like profile management, mod integration, custom JVM arguments, and a user interface for selecting game versions and modpacks. Feature suggestion: Built-in Mod Compatibility Checker Description

Automatically scans installed mods and the selected Minecraft version to detect incompatibilities, missing library dependencies, and deprecated APIs before launch.

Why it helps

Prevents game crashes and confusing error messages. Saves time troubleshooting mod conflicts. Improves user confidence when trying new modpacks. whats sklauncher

How it works (flow)

User selects profile and version/modpack. Launcher scans profile's mods folder and reads mod metadata (fabric/forge/Quilt version, required libs, mod loader). Launcher compares mods' declared supported MC versions and required loader versions against selected profile. For each mod, check for missing dependencies (by name and semver) and known conflicts (from local rules + community-shared database). Present a clear report with color-coded status: OK, Warning (deprecated/untested), Error (incompatible/missing). Offer one-click fixes: download missing libraries, switch to compatible mod loader, disable conflicting mods, or revert to compatible mod versions.

Key UI elements

Compatibility summary banner (green/yellow/red). Detailed mod list table: Mod name | Version | Loader | Required MC | Status | Action. One-click Fix button per issue and global Fix All. Ignore/Force-Launch option with explicit risk warning and crash-report link.

Implementation notes

Use mod metadata standards: Fabric/Quilt mod.json, Forge mcmod.info/manifest. Maintain a small local cache of popular mod metadata; allow opt-in community sync to fetch a shared compatibility database. Respect user privacy: only fetch metadata and mod names; do not upload world saves or personal files. Provide developer API so modpack authors can publish compatibility rules.

Minimal MVP scope

Support Forge and Fabric metadata parsing. Detect MC version mismatches and missing dependencies. Show report and allow disable/download of missing libraries.
